WM8521
Stereo DAC with Integrated Output Stage
for 2Vrms LINE OUT
DESCRIPTION
FEATURES
The WM8521 is a 192kHz stereo DAC with an integrated output
op-amp stage, designed to generate a 2.0Vrms output signal
directly, so reducing external component requirements in digital
audio applications.
WM8521 comes into two variants WM8521HC and WM8521H9
which offers different line drive output capabilities. WM8521HC
outputs 2Vrms at 12V supply, while WM8521H9 outputs
2.0Vrms at 9V supply. WM8521HC/H9 are designed for cost
sensitive consumer digital audio applications requiring 2Vrms
line output.
A 24-bit multi-bit sigma delta DAC is used with oversampling
digital interpolation filters. Digital audio input word lengths from
16-32 bits and sampling rates from 8kHz to 192kHz are
supported.
The audio interface supports I2S, Right Justified and DSP digital
audio formats.
Audio Performance
- DAC SNR 98dB (‘A’ weighted @ 48kHz)
- THD -81dB (‘A’ weighted @ 48kHz)
DAC Sampling Frequency: 8kHz – 192kHz
Pin Selectable Audio Data Interface Format
- I2S, 16-bit Right Justified or 16bit DSP
2.0 Vrms output at 12V or 9V supply
7.6V to 13.2V Analogue, 2.7V to 3.6 Digital Supply
14-lead SOIC Package
APPLICATIONS
Consumer digital audio applications requiring 2 Vrms output
- DVD Players
- Digital TV
- Digital Set Top Boxes
- A/V Receivers
The devices are controlled via a hardware interface which
provides access to features including de-emphasis, mute and
data formats. These devices are pin equivalent and are
available in a 14-lead SOIC package.
